GEORGE L. THOM, OF BROOKLYN, NEW YORK, ASSIG-NOR TO WILLIAM WALLACEMCLAURIN, OF BROOKFIELD, MASSACHUSETTS.

PUNCH.

Application led February 10, 1913.

To all 'whom 'it may concern Be it known that l, Geenen L. Triton, acitizen of the United States, residing at Brooklyn, in the county ofKings and State of New York, have invented certain new and usefullmprovements in Punches; and l do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention is a punch and has for an object to provide a number ofdies carried in a single outfit comprising a pair of operable handles, adie member and a piece against which said die member is adapted to bearafter penetrating the article t be punched.

Figure 1 is a sectional view of a punch constructed in accordance withmy invention having parts thereof in elevation. Fig. 2 is a series ofviews showing the die members in section. Fig. 3 shows the die membersin elevation. Fig. t is a horizontal sectional view showing the cam'faces of the several die members. Fig. 5 is a side elevation of mydevice. Fig. 6 is a side elevation of the punch showing the parallelbars arched for a portion of their lengths adjacent the anvil and diemembers. Fig. 7 is a modified form of an anvil to produce acircumferential movement with respect to the die members.

Referring more specifically to the drawings 10 indicates a pair ofhandles pivoted to one another as at 11 and to parallel members as at12. These parallel members are designated by the numerals 13 and 14 andas shown have the forward ends of the handles 10 secured thereto topermit the swivel movement between these members 13 and 141 and thehandles 10 while the fastening means 12 adjacent the rear ends of thesemembers pass through slots to permit sufficient movement when thehandles are swung together. The member 13 is provided with the head 15in which is mounted a plate 16 which may be of zinc, lead, or any othersuitable material. The member 111 is provided with the head 17 havingthe flange 18 thereabout and having pins 19 secured thereto as shown.

The numeral 20 indicates a screw for holding several parts to the head17 to be hereinafter described. A series of annular Specification ofLetters Patent.

die members 21, 22, 23 and 24: are placed in the cupped head and areprovided with keyways to accommodate the pins 19 so as to permitvertical movement of the die members but to restrict circumfercntialmovement thereof. Any one of the four die members may be disposed topresent its cutting edge beyond the remaining three and this isaccomplished by means of a member 25 having a central portion to receivethe bolt 2O after passing through a plug 26 weich plug is held againstrotation by its engagement with one of the pins 19. The ends of the barsof the member 25 terminate in thumb pieces 27 by which this member maybe manipulated and the ends of this member extend through the slots 28in the wall 1S to limit the movement of the member 25 in bothdirections. To assist in determining which one of the several diemembers is projected by the movement of the member 25, a series of indexfigures 29 may be formed in the wall 18 adjacent to the slots 28. Eachof the several die members may be made of single pieces of material andslotted or they may be made 0f two pieces of metal in view of thedifficulty in treating tool steel. ln any event cams 30 are formed oneach, of the die members so that when the several dies are assembled thecams of the several dies are disposed in advance of the adjacent one sothat the of the member 25 will engage one or another of the pairs ofcams in any position within its movement. The upper wall of each slotconforms .with the lower one so as to return the die member intoinoperative position when that particular die is not desired for usageand in the event of each of the die members being made of two pieces ofmaterial fastened t0 one another in any desired means, the numeral 31indicates the upper piece of each of the dies.

The parallel bars 13 and lll are shown arched for a portion of theirlength as in Fig. 6 to permit the gathering of a quantity of material insaid archedI portions when it is desired to punch a piece of fabric at adistance from the edge thereof.

In the modification shown in Fig. 7, the head 32 has a trunnion 33 whichis mounted in a bearing 341 formed in the socket 35 carried by the bar13. A ratchet 36 is formed on the head 32, and a pawl 37 which receivesits movement by its fastening with the rivet 12 engages a ratchet to setup a partially rotary movement to the head 32 at each manipulation ofthe handles. This paWl may be made of resilient material to eliminatethe use of an additional spring, or the spring 38 may be used tomaintain the engagement of said paWl and ratchet.

Further modifications may be made Within the scope of this inventionsuch as modiied means in moving the several die members With respect toone another as by cam slots in the several die members and lugs carriedby the adjacent die members to engage said cam slots.

Having thus described my invention, l claim:

l. In a punch, movable members, an anvil carried by one of said members,a plurality or" dies carried by the other of said members and means toproject any one of said dies beyond the others.

In a punch, movable members, an anvil carried by one of said members, aplurality of various sized dies nested one in the other carried by theother of said members each of said dies having movement with respect toits supporting medium and means carried by the supporting medium forprojecting any one of said dies beyond the others.

3. In a punch, movable members, an anvil carried by one of said members,a plurality of dies carried by t-he other of said members, each of saiddies having a limited movement with respect to its supporting medium andmeans carried by the supporting medium for extending any one of theseveral dies beyond the others.

4L. In a punch, a supporting member, a

plurality of die members of different diameters, said die members beingnested each of said die members having an irregular surface, saidirregular surfaces of said die mem` bers having stepped relation witheach other and means carried by said supporting member for engaging saidirregular surfaces to extend any one of said die members beyond theothers.

5. ln a punch, movable members, a plurality of dies carried by one ofsaid'memb ers, an anvil carried by the other of said members, and meansfor moving said anvil circumferentially upon manipulation of the punch.

(i. In a punch of the class described, a supporting member having a cupshaped socket formed therein, a plurality of die members of dierentdiameters disposed therein, means carried by said supporting mem-ber toengage said die members to prevent rotation thereof, each of said diemembers having a cam face formed thereon, and rotatable means carried bysaid supporting means for engagement With said cam faces formed on saiddie members to extend any one of said die members beyond the others.

In testimony whereof I aiiix my signature in presence or' tivoWitnesses.
